NRAO VLA Archive Survey

摘要

The Very Large Array (VLA) radio telescope, operated by the National Radio Astronomy Observatory (NRAO), has been collecting interferometric data (visibilities) since the late 1970's. Converting visibility data into images requires careful calibration of the data, fast Fourier transform processing, and deconvolution methods. To make VLA data accessible to the astronomical community, the NRAO has undertaken the NRAO VLA Archive Survey (NVAS). The goal of NVAS is to produce images, calibrated data, and diagnostics from the visibility data archive and make these data products available to all astronomers. Survey results are obtained from a software pipeline, the details of which are described here.
